The Corrupted Characters Checker is a custom QA check designed to identify and flag corrupted or invisible characters in your translations. It scans translations for common encoding issues, such as the replacement character (�), zero-width spaces, zero-width non-joiners, zero-width joiners, control characters, and specific corrupted sequences often resulting from encoding mismatches (e.g., misinterpreted ‘Ä’, en dashes, ellipses). The tool automatically highlights problematic characters and provides suggestions for corrections to ensure your translations are clean and free from unwanted artifacts.
